This press release is on the website of the Death Penalty Information Center:

(Washington, D.C.) The Death Penalty Information Center today released the results of one of the most comprehensive studies ever conducted of Americans’ views on the death penalty. A national poll of 1,500 registered voters conducted by Lake Research Partners shows growing support for alternatives to the death penalty compared with previous polls. A clear majority of voters (61%) would choose a punishment other than the death penalty for murder, including life with no possibility of parole and with restitution to the victim’s family (39%), life with no possibility of parole (13%), or life with the possibility of parole (9%).

In states with the death penalty, a plurality of voters said it would make no difference in their vote if a representative supported repeal of the death penalty; and a majority (62%) said either it would make no difference (38%) or they would be more likely to vote for such a representative (24%).
